UNHTE AUTOMOBILE SIGNALING DEVICE.

7 Application filed May 10,

This invention relates to an improved direction signal for automobilesand has for its object the provision of a signal of simple and ruggedconstruction capable of positive action to indicate clearly topedestrians and drivers of adjacent vehicles the intended movements ofthe automobile provided with the device. y Y

A preferred form of the invention is shown in the accompanying drawingsand described in the specification and appended claims, but it is to beunderstood that changes may be made within the scope of. the claimswithout departing from the spirit of the invention. r

In the accompanying drawing:

Fig. 1 shows the invention applied to the usual type of truck cab orenclosed type of pleasure automobile;

Fig. 2 shows a vertical invention; and I Fig. 3 shows a verticalsectional view taken on the lines A-A of Fig. 2.

Referring more specifically to the drawings in which similar referencenumerals are used to denote similar parts in each of the several views,the reference character 1 indicates a U-shaped supporting frame orbracket which is adapted to be secured to the frame of the vehicle. Thebracket 1 is plan view of the provided at each end with arms 2 and 3,

through which aligned holes are drilled to receive a shaft 4, the latterbeing capable of both sliding and rotating movements. One I end of theshaft 4 is bent at a convenient angle to the axis of the shaft to form ashank 5, to which an operating handle 6 is attached. A notched disk 7 ismounted upon the shaft adjacent to the arm 3, this disk having formedintegral therewith a hub or collar 8. The disk is held against relativerotation on the shaft by means of a set-screw extending through thecollar. The disk is spaced from the arm 3 by a washer or collar 10loosely mounted on the shaft.v A pin 9 is mounted on the arm 3 in aposition to cooperate with the notches in the disk 7 to hold the shaft4; in the various positions desired. Upon the shaft 4 is a coil at'spring 11 under compression, abutting one end against a stationary disk12 fixed to the shaft by a pin 13, the other end'of the spring abuttingagainst a loosely mounted collar 14. Reaction to the compressive r forceto which the spring 10. is subjected tends to slide the shaft {1 towardarm 3 and 1927. Serial No. 190,183.

thereby maintain the pin 9 and the notches of disk 8 in locked operativerelation.

A semaphore 15 is rigidly fixed tothe outer end of the shaft 4 between acollar 16 and a nut 17. Plates 18 and 19 are fasa tened to arms 2 and 3to support and reinforce as wellfas to furnish larger bearing surfacesfor the shaft 4 in said arms.

The semaphore 15, is, of course, so placedthat it will project beyondall portionsof the truck cab or automobilebody so as to be entlrelyvisibleto any adjacent drivers of vehicles. For convenience in theadjustment of the semaphore to the desired angles 7 used to give theindications as to the differ ent directions or other motions of thevehicle which are to be made, the semaphore and the handle arepreferably arranged in a parallel relation in'the same plane, so thateven though the semaphore may be beyond the vision of the driver of thevehicle to which it is attached, a glance at the direction of the handlewill indicate to him the exact direction in which the semaphore points.Consequently, the location of the 7 device may be, varied between verywide ranges, since it is unnecessary for the semaphore to be within thedrivers range of VlSlOIl.

In operation, the shaft 4 is moved to the left, as viewed in Fig. 2 bypressure upon the spring, thus disengaging the pin 9 from the notch inwhich it rested. By rotation of the shaft while thus. disengaged, thesemaphore may be rotated to the desired position of angular adjustmentnecessary to give the appropriate signal. Release of the pressure putupon the spring will automatically return the shaft to its originalposition where it becomes locked until the operator changes theposition.

Having I claim is:

1. In a vehicle signal, .a one-piece U- shaped bracket having arms'and aconnecting portion capable of attachment to the frame of a vehicle,.ashaft rotatably and slidably mounted in the arms of said bracket, a coilspring under compression on said shaft, a notched disk fixed to saidshaft adjacent to one of the bracket arms, a pin on thus described myinvention, Wllflth the adjacent arm in position to normally engage oneof the notches in the disk, a semaphore on one end of said shaft, meansfor holding the semaphore and shaft against relative'movemennand ahandle at the other end of said shaft for operating the latter,

said disk being moved relatively to said pin the ad ustment of saidsignal.

vehicle signaling device comprising spaced bearing members, a shaftrotatab and slidably mounted in said bearings,

means for locking the shaft against rotation, the said locking meanscomprising a disk having a plurality of notches therein and 0 fixed tothe shaft adjacent one of and between said bearing members, a pinmounted "to selectively cooperate with when the shaft is in oneposition, spring. means for urging the shaft ina directlon on theadjacent bearing member and adapted said notches to cause engagementbetween the in and the notches, a handle for moving t e shaft in adirection against thespring means 'to the pin and notch and to rotateafter disengagement, and a semadisen a e the sha the other end of saidshaft for rotating the latter, said disk being moved relatively tosaid'pin during the adjustment of said sig nal. v 1 7 i In testimonywhereof I afiix my signature.
